    Flatfoot deformity has large individual differences. Therefore, surgeons have to choose appropriate surgery for individual patients. In this paper, we introduced a finite element (FE) model of flatfoot. This model was used to study the influence of different surgeries. We aimed at providing useful information to the surgeons through simulation prior to real surgery. This paper presented the modeling procedure and two examples of surgical simulation. Results validated the feasibility of using FE simulation to study the influence of different flatfoot surgeries.

    CS-MRI is a high-speed magnetic resonance imaging technique based on compressed sensing theory. It is known that the utilization of dictionary learning (DL) for CS-MRI leads to better image reconstruction results. In the optimization problem adopted by the DL-based CS-MRI, we must appropriately adjust the weights of data fidelity term and dictionary fidelity term, respectively, for each MR image. In this paper, we formulate a novel optimization problem where the above two fidelities are expressed as level set constraints, and solve this optimization problem by using alternating direction method of multipliers (ADMM). Numerical experiments show that the proposed method can reconstruct several MR images with high accuracy by using the same parameters.

    Interfaces for people with severe motor impairments that enables them to interact with a healthy person and manipulates a wheelchair by extending the body motion ability through information equipment recently has been put to practical use. It is well known that tongue and gaze motion can remain even in much serious stage. It is a problem to assure the electric insulation of the device in oral cavity. In this research, we propose a pointing I/F using the intraoral image taken by a small camera for the endoscope available at low cost. Since the individual movement of the tongue is largely different according to disease condition and it may changes over time, a learning signal to the CNN is dynamically generated and adapted to ensure the invariant operative output range.

    In this paper we aim to determine what factors encourage people to walk. Our approach consists of two phases. We firstly extracted factors affecting walking from questionnaires. We then analyzed the relationships between two factors, weather and weekday/holiday, and the number of the steps. The result showed there are several patterns and the findings would be beneficial for habituating people to walk.

    I have developed a data reduction system for points data. The system generates lightweight data by collecting images which are rendered the original point data from multiple directions. The data size of the generated data depends on two parameters: the window resolution at the rendering and the number of directions. Therefore, users can control the data size without the dependency of the complexity of the original data. I have implemented the prototype system and the effect of the two parameters was clarified. At the test, about 26 million point data was reduced to about 2% size with enough quality. The average PSNR value calculated from the images that were obtained from 26 directions rendering of the both data, the original and the reduced, was indicated over 70dB.

    This paper investigates global circulation and entanglement of designs in the textile printing in the 19th and 20th centuries. For this purpose, the paper focuses on “African prints” and Japanese stencils called katagami. While their original printing techniques are different from each other, these running patterns can serve as design sources for machine printing. While they are seemingly unrelated to each other, the investigation re-veals their global linkage, not only historical but also complex, in terms of printing designs.

    In recent years, as the Web technologies have matured in more and more countries, many cultural memory institutions, such as libraries, museums and cultural heritage organizations, all around the world begin to digitize their collections and provide them on the Internet with metadata in different languages. With the emergence of multilingual digitized collections, it opens up new opportunities but at the same time poses language barriers for accessing these large quantities of digitized collections. In this paper, we propose a method to find the identical Ukiyo-e prints between databases in different languages by exploiting semantic similarity of metadata across languages, in order to achieve our ultimate research goal that aims to provide multilingual access to multiple and diverse databases. We believe our proposed method could assist users in accessing Ukiyo-e databases regardless of languages.

    This paper introduces our approach in providing integrated access to multiple Japanese humanities databases. We propose a federated search system, which retrieves multiple databases in parallel through a single interface and provides real-time integration of retrieved results. Such a system along with a facility for cross-language search between English and Japanese is useful for users who are looking for materials in Japa-nese databases that are mostly available in Japanese, in which users who do not understand Japanese may not find the desired information. Using the proposed system, users get better results than the native database’s search interface. Even though the same content is being searched, the proposed system enhances the retrieved results. Users are provided with faceted navigations, unified search results of bilingual data holding basic in-formation, and links where the original records along with detailed information can be found. Faceted naviga-tions offer a new way of finding and browsing databases as an addition to the typical keyword searching and browsing. We applied the proposed system to the public versions of humanities databases of Art Research Cen-ter at Ritsumeikan University, which has been constructing digital archives of tangible or intangible heritages of Japanese arts and cultures.

    In this study, we attempted to set the target value of the number of steps of the subject based on statistical changes in the body composition index. For that purpose, we conducted two analyzes. In analysis 1, the target value of the number of steps of the subject was set on the premise that it would be a safe and convenient value. We also conducted a cross-sectional study between subjects, and it was found that the visceral fat level was statistically lower in the group with many records than in the group with only a few records. In Analysis 2, longitudinal study was conducted, and it became clear that those who are in the higher group statistically lower the visceral fat level after 4 months.

    In this study, we extract several in-week and -day patterns in ambulatory activity and body composition change from a big data of activity monitor and body composition meter records. For ambulatory activity, we apply a hierarchical topic model, composed of two layers of in-week patterns as super-topics and in-day patterns as sub-topics, to aggregated records of step counts. As a result, four diurnal activity patterns named commuting, morning, daytime and night activities are extracted as sub-topics and several combinations of these patterns within a week are extracted as super-topics. Using in-week and -day patterns extracted in the analysis, we discuss dynamical relation between ambulatory activity and body composition change.

    This paper proposes the user interaction design for digital signage displaying health information. Recently, digital signage has gained popularity placed in public facilities or stores to show advertisements or guidance information. However, users become used to the displayed information followed by the time course and the interest and usage decreases. To solve this issue, this paper proposes a digital signage system which users can interact to obtain health information. There can be many interaction methods for the use and digital signage, although, for sustainable usability, useful interaction methods are limited to several methods not requiring many user actions. In this paper, three types of interaction design are introduced, depending on the target user behavior.
